This report updates ACEEE's 2013 assessment of multifamily energy efficiency programs in US metropolitan areas with the most multifamily households. Using housing, policy, and utility-sector data from 2014 and 2015, this report documents how these programs have changed in the context of dynamic housing markets and statewide policy environments. The report also offers an analysis of the number, spending, offerings, and targeted participants of current programs and their potential for further expansion.

The work presented in this webinar is a collaborative endeavor by the ARIES Building America team and two major affordable housing providers: Habitat for Humanity International and the factory building industry. The effort is exploring options for making major reductions in space conditioning energy use (≥ 50%) while holding the line on home affordability. Specifically, the project will develop a high-performance integrated design--effectively combining an ultra-efficient thermal envelope, a very low capacity, highly efficient mechanical system, an innovative distribution system, and affordable heat recovery ventilation--and set in motion steps to rapidly move this innovation to market.

This report details opportunities for scaling up program activity and increasing savings from programs reaching the people who need it most. It discussed best practices from existing programs for overcoming many of the key challenges that program administrators face, including how to address housing deficiencies that prevent energy efficiency upgrades, how to address cost effectiveness challenges, and how to serve hard-to-reach households.

The report, based on U.S. Bureau of Labor Statistics data and a survey of tens of thousands of businesses across the country, provides detailed breakdowns of clean energy jobs not available previously, and it was developed and released in connection with a major U.S. Department of Energy study of all energy jobs in America.

Through field-testing and analysis, this project evaluated whole-building approaches and estimated the relative contributions of select technologies toward reducing energy use related to space conditioning in new manufactured homes. Three lab houses of varying designs were built and tested side-by-side under controlled conditions in Russellville, Alabama. The tests provided a valuable indicator of how changes in the construction of manufactured homes can contribute to significant reductions in energy use.

This report discusses indoor air quality issues, including: wildfire smoke, dampness, and mold, and the effect of energy efficiency upgrades on these health-related issues. The report describes current state policies and programs in these areas, highlighting approaches for consideration by other jurisdictions.

Energy burden is the percentage of household income spent on home energy bills. In this report, ACEEE, along with the Energy Efficiency for All coalition, measures the energy burden of households in 48 of the largest American cities. The report finds that low-income, African-American, Latino, low-income multifamily, and renter households all spend a greater proportion of their income on utilities than the average family. The report also identifies energy efficiency as an underutilized strategy that can help reduce high energy burdens by as much as 30%. Given this potential, the report goes on to describe policies and programs to ramp up energy efficiency investments in low-income and underserved communities.

Energy efficiency is good for you--and for the air you breathe, the water you drink, and the community in which you live. This fact sheet shows how saving energy reduces air and water pollution and conserves natural resources, which in turn creates a healthier living environment for people everywhere. It includes the stories of a family in Pennsylvania and a hospital in Florida.

This case study presents information about the AlabamaWISE program. It includes background information, approaches the program took to enhance home energy efficiency, and results achieved by the program.

This report summarizes ongoing and recent policy developments that support utility investments in energy efficiency, including program cost recovery, fixed cost recovery, and performance incentives for electric utilities on a state-by-state basis.

In this video interview segment, Elizabeth Galante of NOLA WISE (New Orleans, Louisiana, Worthwhile Investments Save Energy), describes the program's home energy showcases, which were a successful marketing initiative that helped entice homeowners to undertake home energy upgrades.

This peer exchange call summary focused on how programs are devising plans for creating a contractor revenue stream and potential fee structures.

This peer exchange call summary focused on the challenges and effective combinations of quality assurance strategies.

This market assessment for the Alabama Energy Revolving Loan Fund identifies the customers and potential demand for an energy efficiency upgrade financing program.

This brief focuses on loan programs in 30 states that are currently providing low- to no-interest loans to finance energy efficiency improvements--from energy-efficient windows to replacement HVAC systems--in the residential, business, and public sectors.
